What are the 4 bases that make up the structure of DNA?

Answer 1

DNA (Deoxy ribo-nucleic acid) is made up of structures known as nucleotides, there are four nucleotides from which all the DNA coding has been written, which are as follow :

adenine (a purine)

cytosine (a pyrimidine)

guanine (a purine)

thymine (a pyrimidine)

Answer 2

DNA is made up of four nucleic acids: guanine (G), cytosine (C), thymine (T) and adenine (A). (Nucleic because DNA is found in the nucleus of the cell.) Because of the structure of these nucleic acids G & C bond together, and A & T bond together. That appearance of G, C, T, or A in a string of a DNA molecule are ordered by their connection to a string of sugar molecules. Where a G appears on one side of the helix, a C appears on the other side, and vice versa. Likewise, for the A and T. Thus, the "double" helix - the appearance of the one side of the helix is mirrored by the complementary nucleic acids on the other side.

The basic elements, from the Periodic Table of elements, of life were always taught in my day as CHON - carbon, hydrogen, oxygen, and nitrogen. The magic ingredient that helps these elements create energy (and thus, life) in their various combinations in living organisms is (usually) phosphorus (P). Other elements may be present in various cells or parts of cells, but these are the ones that comprise the basic building blocks of living things. On this planet. So far. Probably. ;-) Gotta love the "certitude" of science!

Answer 3

The four bases that make up the structure of DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). Adenine pairs with thymine, and cytosine pairs with guanine in a double-stranded DNA molecule.

Answer 4

adenine+guanine=purines

cytosine+thyamine=pyrimidines

adenine base pairs with thymine and cytosine base pairs with guanine.

Answer 5

Uracil Guanine Adenine and Cytosine
